TO ALL WIIOM IT MAY CONCERN:

Be it known that I, IVILLIAH IT. CLARK, of Chester, in the county ofMiddlesex, in the State of Connec` tient, have invented a new andimproved-Mode of Hanging the Rudder of Boats and Vessels; and I dohereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon.

The-nature of my invention consists in providing the stern of a boat orvessel with a metal plate, having a groove enlarged inwardly, whichgroove is to receive a corresponding tongue, to which the rudder ispermanently hinged, thereby hanging the rudder; and also in providingthe tongue with extensions for hanging a. balance rudder.

To enable others skilled in the art to make and use my invent-ion, Iwill proceed to describe'its construction and operation.

In place of the devices now used for hanging ruddcrs'I attach a metalplate having a dove-tailed groove, or a groove enlarged inwardly, intewhich groove I fit a corresponding metal tongue, to which the rudder ispermanently attached by any suitable hinge.

Figure 1, of the accompanying drawings, is the representation ofa-rudder hung according to my invention. B represents the stern of aboat to which a metal plate, IP, having a dove-tailed groove, g, isrepresented as attached by screws passing through the extensions in theplate, represented at e e e in Figure 2, which is a representation oftheplate detached. T represents a tongue, dove-tailed to correspond withthe groove gin the plate, and provided with strap-eyes, shown at S S SS, through which the straps a a pass, and are attached to the rudder R,permanently hiuging the rudder to the tongue, whereby it follows that tounship the rudder, the tongue must be withdrawn from the groove in theplate upwardly, the groove being slightly enlarged upwardly, as shown,and shipped by the reverse process. I insert a pin in the tongue nearthe top, which enters the recess provided for itin thetop of the plate,and fixes or limits the distance the tongue may enter. The pin is markedo in Figure 3, which is a representation of the tongue detached. Figure4 is the representation of the tongue provided with extensions for abalancefruddcr, which are marked n n. The extensions upon the tongue, bybeing carried out, will enable the rudder to be hung in the centre tobalance it, if desired. When the head of the rudder to be hungrshipsthrough a rudder port, of course the tongue cannot Wholly be enteredfrom the top of the groove; in that case, instead of making thecorresponding enlargement or dove-tail of the tongue continuous, I makeit in sections, and construct the plate with corresponding ports oropenings to receive them, from which the dove-tailed sections enterthcircorresponding grooves in the plato instead of being passed in from thetop of the groove.

With the arrangement heretofore known and used for hanging rudders ithas been more or less diiicult to readily ship the rudder of a smallheat, in 'consequence of one of the hinges being below the surface ofthe water. This makes it diicult to eiect the connection of the hingeswhen the Water is rippied or not clear, and especially diicult in thenight, when the wavesare striking against the rudder, and the connectionis not sure in rough weather, while-the liability of the rudder to getunhingcd by contact with thc shore, and by various other causes, makesit necessary that it should be unshipped when not in use. By my improvedmode of hanging, the rudder may be readily shipped under allcircumstances, and is .securely hung. Y

What I claim as my invention, and desire to secure by Letters Patcnt,is

The plate P and tongue T, incombination with the hinged rudder R,substantially as herein described aud for the purpose specified. i
